“…The LOCHI study provides comprehensive data for examining the relationships between different outcomes and predictors, and incorporates randomized controlled trials of hearing aid prescription and cochlear implantation. When assessed at five years of age, the children in the study whose hearing loss was discovered at birth and who received early intervention had better spoken language abilities than those whose hearing loss was discovered later [51]. On average, children fitted with hearing aids before six months of age had higher language scores than those fitted later.…”

“…At the moment, a lot of attention is being directed at the information coming out of the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study [51] in Australia. The LOCHI study is a population-based longitudinal study that prospectively evaluates the development of a group of Australian children with hearing loss as they progress in age.…”

This article provides background on the major perspectives involving the development of English language and literacy with respect to the evolving demography of d/Deaf and hard-of-hearing children and adolescents. It synthesizes research and controversies on the developmental similarity hypothesis—that is, whether the acquisition of English language and literacy of d/Deaf and hard-of-hearing students is developmentally similar to that of typical language/literacy learners. The outcomes of this discussion have instructional implications and proffer guidelines for teacher preparation programs. The article concludes with directions for further research.

“…Recent large-scale, population based, longitudinal studies provide convincing evidence for the positive long-term effects of universal NIHS programs on language, cognitive, and academic development of children and adolescents. For example, the Australian Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study [31,32] demonstrated that the earlier treatment with hearing aids or cochlear implants was started, the better the speech, language, and functional performance outcomes of children who are deaf or hard of Effective strategies for preventing hearing loss include reducing the incidence of infections such as rubella, meningitis, cytomegalovirus, mumps, measles, and otitis through immunization, hygienic measures, timely medical and surgical treatment, mother and child health programs, and reductions in the use of ototoxic agents [18]. For example, the risk of a cochlear injury from ototoxic antibiotic medications with aminoglycosides in the fetal, neonatal, and infant periods is especially high, depending on application, dosage, previous aminoglycoside treatment, kidney function, pre-injury of the inner ear (e.g., by syndromes or asphyxia), presence of anemia, familial and individual sensitivity, age, environmental noise, and combination with other ototoxic or nephrotoxic medication [23].…”

Recent prevalence estimates indicate that in 2015 almost half a billion people—about 6.8% of the world’s population—had disabling hearing loss and that prevalence numbers will further increase. The World Health Organization (WHO) currently estimates that at least 34 million children under the age of 15 have disabling hearing loss. Based on a 2012 WHO report, approximately 7.5 million of these children were under the age of 5 years. This review article focuses on the importance of high-quality newborn and infant hearing screening (NIHS) programs as one strategy to ameliorate disabling hearing loss as a global health problem. Two WHO resolutions regarding the prevention of deafness and hearing loss have been adopted urging member states to implement screening programs for early identification of ear diseases and hearing loss in babies and young children. The effectiveness of these programs depends on factors such as governmental mandates and guidance; presence of a national committee with involvement of professionals, industries, and stakeholders; central oversight of hearing screening; clear definition of target parameters; presence of tracking systems with bi-directional data transfer from screening devices to screening centers; accessibility of pediatric audiological services and rehabilitation programs; using telemedicine where connectivity is available; and the opportunity for case discussions in professional excellence circles with boards of experts. There is a lack of such programs in middle- and low-income countries, but even in high-income countries there is potential for improvement. Facing the still growing burden of disabling hearing loss around the world, there is a need to invest in national, high-quality NIHS programs.

“…Ching's recent article is congruent with the above findings. 38 The cochlear implant has created an entirely new area of medicine. For the first time, the structure and function of the central nervous system is being deliberately shaped as a medical intervention by the introduction of electrically induced afferent signals to a central nervous system that had previously not been stimulated or had ceased to be stimulated by sound.…”

ObjectiveTo access the long‐term outcomes of children implanted during most sensitive period for language development.Study designLiterature review.MethodAn initial PubMed search was carried out using the search terms language development and cochlear implant resulted in 1149 citations. A second search was carried out on the initial citations using the criterion of implantation in the period of birth to 24 months, which identified 386 articles. These were analyzed to determine those studies in which linguistic outcome was measured at least three or more years following implantation.ResultsTwenty‐one reports published from 2004 to 2017 that met the criteria. The range of follow‐up was from 3 years to an excess of 10 years. Four => 10‐year follow‐up reports were consistent in showing that the earlier the subject is implanted the better the outcome. Many, but not all, of these children did obtain age‐appropriate language. There were 17 reports with follow‐up from 3 to less than 10 years. In 7 of the 11 studies, the children's expressive language was reported to have reached an age level of less than 80%. The results for receptive language showed that 4 of the 11 studies found that the children achieved a receptive language age level of less than 80%. There were 8 studies which documented the effect of implantation before 12 months of age and between 12 and 24 months of age and they all found that the earlier the implantation, the better the outcome for language.ConclusionThe cochlear implant is efficacious in the amelioration of receptive and expressive language deficits in most congenitally deafened children implanted before the age of one. The language outcomes for those implanted after the age of one decline as the age of implantation increases.Level of EvidenceN/A.

Learning from the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study: summary of 5-year findings and implications

Abstract: The LOCHI study has shown that early fitting of hearing devices is key to achieving better speech, language and functional performance outcomes for children with hearing loss. The findings are discussed in relation to changes in clinical practice and directions for future research.
